Walk down to the waterfront by echo museum and catch a sunset by the boardwalk.

Ben & Jerry's in Waterbury (they might not be doing tours still though)

Al's French Fries is very mediocre but it's a James Beard award winning restaurant. Eat there and wonder why. (their fries are pretty good. Nothing else on the menu is. It's tradition to put white vinegar on the fries there)

You could eat out every night at a non-chain restaurant and still not get all the good ones.

Go hike mount Philo.

If you want to make a religious pilgrimage, Joseph Smith's birthplace is less than 90 minutes away and has a monument and visitor center and nice grounds.

The VT teddy bear company tour is cool.

The band Phish used to play at nectars before they made it big, you can go eat there.

Burton store has Burton stuff.

What kind of stuff are you interested in?
